The original Jamshidi needle by CareFusion offers features that have made this bone marrow biopsy/aspiration needle a best seller for decades. Its lightweight handle with built-in comfort knob enables the practitioner to apply sufficient pressure without discomfort. The tapered distal tip facilitates the recovery of bone marrow samples with unaltered architecture and a razor-sharp bevel tip allows easy coring of the bone. Its single-use design helps assure sterility for every procedure and helps prevent cross contamination.. The needles are available in a wide variety of sizes and tray configurations to meet user preferences. All needles are packaged with an adapter to accommodate luer lock syringes.
